Air-Bearing Rotary Tables
ABTech’s standard line of high precision, air-bearing rotary tables (AT Series) and heavy-duty rotary tables (HDRT Series) are ideal for low-speed TIR measurements, optical inspection, precision assembly, or light machining and grinding where radial and axial accuracies down to 2.0 µ” are required. These are available with tilt and center worktables, precision fixtures, 3-jaw chucks, vacuum feed through the center, and motor drives. They are manufactured with 440CSS and hardened to 58 – 60 RC, making these rotary tables the most robust available.

Oil Hydrostatic Rotary Tables
More than 4 times stiffer than air-bearing tables, oil hydrostatic rotary tables are ideal for the most demanding high precision machine tool applications. If extreme stiffness and high load capacity are essential to your application, let our staff help you select the right oil hydrostatic rotary table. Our systems include the hydrostatic power unit (HPU) which consists of a low-speed precision pump, pressure sensor for closed-loop operation, filtration system, and reserve tank.

Mechanical-Bearing Rotary Tables
When the air-bearing level of precision is not needed, we offer a wide variety of precision mechanical-bearing rotary tables. Offering high load capacity and stiffness with radial and axial accuracy to 40 µ” (1 micron) or less, these are ideal for low speed TIR measurements, inspection, precision assembly, or light machining and grinding. Available with tilt and center worktables, precision fixtures, 3-jaw chucks, and motor drives.
